A lamp that runs eight hours on water and salt

A start-up in Philippines in July 2015 developed a lamp named SALt (Sustainable Alternative Lighting) that runs on a glass of water and two tablespoons of salt. The lamp is named after the company SALt that was founded by Aisa Mijeno and Raphael Mijeno.This cost effective lamp burns for eight hours at a time to lighten a room and will also be able to generate enough energy to charge a smart-phone through a USB cable.

The lamp can also be lit by using ocean water and would be of great help for people living along the coastline.

How it will work?

The lamp works with a galvanic cell battery, which consists of an electrolyte solution - the salt and water - and two electrodes. The electrodes, after being placed in the electrolyte, generated energy that can lit an LED light.

The battery will work for eight hours a day for six months, which is a considerable upgrade from the constant refills required by paraffin lantern.

The team says that the lamp is safe as there are no materials and components inside the lamp that may cause fire accidents.

The start-up hopes that the lamp will be in the market by 2016.

The idea to develop such a lamp was conceived during their stay with the natives of the Butbut tribe of Philippines for days that relied only on kerosene lamps and moonlight to do evening chores.
